T 0 all whom it may conceive.:

Be it known that l, Chartres Sni'rn, a citizen of the United States, residing at Boston, county of Suffolk, and State of Massachusc tts, have invented a certain new and useful 1mprovement in Door l-"asteners and Openers,

`of which the'following is a specification, rei'- erence being had therein to the accompanying drawings.

'lheinvention relates to a new door fastener and opener.

The special object of the invention is' to provide a fastener which shall also serve as an automatic safety lock which can be opened from without by means of a key or by a person in another room by means of an electrical connection, but the invention is also adapted foruse a door fastener which may he opened from either side of the door by any one without a key and without inaking electrical connection by simply pushing the knob on one side or pulling the knob on the other side without turning the shaft. 1f the lock is employed, the door can still he opened by a person on the insideI without a key or making electrical connection.

1f the lock is electrically released, the

catch or fastener can then be released and the door opened from the outside by pushing thc door without turning the knob, and if the lock is released by a key, the key also moves the shaft axially so that the door may be opened by a straight push. 1n whatever form the fastener is employed in the preferred form of construction, no radial Inovement of the key, knob or shaft is required,- the unlocking and the opening of the door is all done by a straight push from one side or straight pull from the other side.

l/Vhile 1 prefer the form of construction in which a straightline pressure is all that is `required to unlock as well as to' release the catch and open the door, yet the invention may be embodied in a form in which the lock is released by a turning movement of the shaft and the catch released from the keeper by a straight line pressure. 1n the drawings-Figure 1 is an. end elevationof a door, partly broken away, fitted with my new lock, knob on one end of the shaft and key inserted, the inner end of the shaft being broken oil". 'F.g. 2 is a vertical section of saine taken through the knob, the inner knob being omitted but the shaft being shown full' length i'itted for a door knob. Fig. 3 is a view in elevation looking into the lock, one of the side platesot` the lock case being removed. Fig. 4 is a section takenpaline 4-4 of Fig. Fig. 5 is a view in elevation of the same showing the locking catch thrown hack as when the door is being opened. Fig. Gis a planview of Fi 5. Fig. 7 is a View on line 7 7 of Fig. 2. gliig. 8 is a sectional view showingv the invention employed as a fastener alone without the lock. Referring to the drawings, 13 represents a door (partly broken away) fitted with my new fastener which is mounted in a case 14 mortised into the door.

A 'catch 4 of the `usual triangular form in cross-section having an inclined cam face 4 is adapted to engage with a socket 15 in the `door casing 16 and is hingedtoa vertical v plate 17 by a vertical ivot 5 at the junction ofthe two right line sii es ofthe catch so that the catch is adapted to be turned on its pivot a quarter turn from the locking 'position shown in Fig. 4 (in which the catch protrudes from the case) into the position shown in Fig. 5, so that the catch is wholly within the caso. The pivot 5 is provided. with a spring 1S which normally holds the catch in the position shown in Fig. 4 relative to the plate 17. The plate 17 has a sliding movement whereby the catch 4 and all the other parts attached thereto which will be hereinafter' described may be moved rearward from the position shown in Figs. 3 and 4, so that the catch 4 has a double movement, that is, a quarter turning movement on its pivot and a sliding movement with its supporting plate 17 A horizontally extending lever 3 is pivoted intermediate et its ends at its upper and lower edges as by a pivot 19 in the ears 20 which project horizontally from the plate 17, so that the lever 3 may be turned in a .horizontal plane whenever it is left free to turn, but i't is normali prevented fromv turning by means of a locking lever 2 pivoted at 21 which engages a downwardly turned-finger 22 of the rear arm of the lever 3.""The locking lever 2 isnormally held in engaging position by a' spring 30.

A lover 6 is pivoted at one end at 23 to .the catch 4 and extends rearwardly being formed in its rear portion with a bent arm 12 which engages the side ofthe lever 3, and is also formed with a shoulder 25"which en gages a cani surface 26 of a projection on the side of the lever 3. When the dooris being opened, the catch 4 is turned on its pivotbyl to receive a key 45, preferably el the Yale does not turn.

end wall 40 ot' the head 37 and limits the out- Ward movement of the rod 34 and barrel 36. The head 37 may be provided with a flange 41 and securnl to the door by bolts 42 and )rovided with a knob or handle 27, The. Y arrel 36 is provided with a thin key slot 44 lock style, the key being ioiimed with a. shoulder 46 whii h engages with a shoulder 47 on the barrel 36 near its outer end, whereby by continuing to push the"-key also moving the shalt 7 inward to release the lever 2 as already described. The barrel 3 is recessed near its inner end to receive a coil spring 48, one end ot which abuts against the barrel, and the other abuts against the 'lixed end wall 4() ol the head 3'( so 'that when the inward pressure of the key released, the spring will force the barrel outward again to its normal position. ',lhe spring seated pins of well known useonly in ordinary construction the key turns while in my device the key `Vith the construction already described, therefore, there are three ways of unlocking the door: iirst, it may be opened lroni the inside simply by a straight pull on the handle ond, it may be unlocked at any distant point wherever there is a. circuit-closer connected. with the wires leading from theopposite poles of the electro magnet, and when thus unlocked, a person at the outer side ol the door can open it by simply pushing inward or by pushing directly on the door; third, a person having a key can insert it in the key slot and by a straight push release the lock and then by a still further direct pressure en It isobvious that the key controlled iiiecle trical mechanism, or vice versa, if desired. If it is des1red to use the device merely as a door latch or 'fastener so that any one can nection, the outer end et the shalt 7l may be litted with a handle 50 by which the shalt can be pushed in directly to release the locking lever, vas shown in Fig. 7. A spring 5l is provided to retract the shaft when the inward I have described the shalt 1 as having only movement', that is all that is necessary lor tudinal movement because a straight push is the ,door without necessity ol' turning a knob.

were mad-e rotatable instead of axially niovable', a cani niight be mounted on the shalt which upon turning the shaft would engage the. lever 2 and turn it on its )ivot so as to release it from the lever 3 and t ien by a straight push on the door the catch 4 would be tui-ned on its pivot and allow the door to open.

'lhe main :te atures of the invention are iirst the hinged catch 4 on the door, and means 'for normally holding it in engagement with the socket in the door casing which will yield to direct pressure on the door, and secondly, when. desired to-use it as a lock, to have a locking lever which normally holds the catch so that it cannot `yield to pressure on the door until the lock is released, and after the lock is released, the catch will still hold the door fastened until released by a straight push or pull, the particular' forni of means 'lor releasing the lock being oi` less iinportance.
